LITTLE ROCK (AP) — Arkansas Attorney General Dustin McDaniel has rejected a request to certify the popular name and ballot title of a proposed constitutional amendment that calls for ending a prohibition on marijuana.

McDaniel rejected the request from Arkansans For Medical Cannabis in an opinion on Friday because he said there were ambiguities in the text.

The proposed measure must be certified by McDaniel before the group can begin gather5ng signatures in an effort to qualify for a spot on the 2014 ballot.

McDaniel has certified the popular name and ballot title of one of two proposed initiated acts that would legalize medical marijuana.

The proposal from Arkansans For Medical Cannabis calls for ending a prohibition on the cannabis plant, not just legalizing medical marijuana.
